I am a backend-focused engineer obsessed with building high-performance, data-intensive microservices and real-time systems that handle massive scale. I focus heavily on low-latency architectures, containerization, and cloud automation.

• 🏎️ Designed and optimized production backends handling 4,500+ Requests Per Second (RPS).
• 📡 Maintained ultra-low ~100ms latency thresholds across regional networks for real-time systems.
• 👥 Developed consumer and enterprise tools actively trusted by 3,600+ users.
• 🛠️ Scaled an inventory mobile app's performance, crashing execution lag from 5s → 0.5s.

• Built a high-concurrency voice/video calling engine using WebRTC and custom WebSocket signaling backends in Go.
• Handled 4,500+ RPS with ~100ms latency across Asia regions.
• Integrated intelligent AI conversation personas with ultra-low latency speech-to-text (STT) and text-to-speech (TTS) streaming pipelines via Groq AI.

• Architected a modular microservices B2B marketplace driven by a secure, custom-built entry-point API Gateway.
• Implemented token-bucket rate limiting, high-performance full-text search indexing via Typesense, and automated multi-tenant asset pipelines using Cloudflare R2.

• Deployed serverless cloud infrastructure on AWS (Lambda, EventBridge, API Gateway) serving 3,600+ active users.
• Engineered automated cron-trigger workflows to dispatch push alerts exactly 5 minutes before events using Firebase Cloud Messaging (FCM).
